Working Papers


The Geography of Innovation in the United States
(Job Market Paper)


Research Question: What drives the rising spatial concentration of innovation from the early 1990s and what are the aggregate consequences?


Methodological Contribution: Introduce endogenous, directed, and microfounded innovation in a dynamic spatial model


The Economic Effects of Climate Change in
Dynamic Spatial Equilibrium

(joint with Ivan Rudik, Gary Lyn, Ariel Ortiz-Bobea)

R&R, Journal of Political Economy: Macroeconomics

Research Question: What are the welfare effects of general equilibrium adaptation via trade, migration, and capital accumulation in response to
climate change?

Methodological Contributions: (1) Model-consistent estimating equations to identify climate impacts on productivity and amenities from temperature shocks; (2) Quantitative decomposition of general equilibrium adaptation channels (trade, migration, industry switching, capital accumulation) to shocks in fundamentals in a dynamic spatial model


Work in Progress
